SaaS Metrics

Monthly recurring revenue (MRR) is the predictable, normalised revenue a subscription business earns each month. It is the single most important metric for understanding the health and trajectory of a SaaS company because it captures new sales, expansion, contraction, and churn in one number.

Annual recurring revenue (ARR) is the annualised value of a company's recurring subscription revenue. It is the primary metric used to measure the scale and growth trajectory of SaaS businesses, and it directly drives enterprise valuations.

Average revenue per user (ARPU) measures the mean revenue generated per user or account over a given period. It is a critical metric for understanding monetisation efficiency and for connecting pricing strategy to revenue outcomes.

CAC payback period measures the number of months it takes for a customer to generate enough gross profit to recoup the cost of acquiring them. It is a critical measure of capital efficiency and cash flow health in subscription businesses.

The LTV:CAC ratio compares the lifetime value of a customer to the cost of acquiring them. It is the most fundamental measure of unit economics and determines whether a business can grow profitably.

The Rule of 40 states that a healthy SaaS company's combined revenue growth rate and profit margin should equal or exceed 40%. It balances the tension between growth and profitability, providing a single benchmark for overall business health.

The SaaS magic number measures how efficiently a company converts sales and marketing spend into new recurring revenue. It answers the question: for every pound invested in go-to-market, how much new annualised revenue does the business generate?

The SaaS quick ratio measures the efficiency of MRR growth by comparing revenue gained (new + expansion) to revenue lost (churned + contraction). A high quick ratio means the business is growing efficiently without relying on brute-force acquisition to outrun churn.

Expansion revenue is the additional recurring revenue generated from existing customers through upsells, cross-sells, add-ons, and usage growth. It is the most capital-efficient source of growth because it requires no acquisition cost.

Burn rate measures how quickly a company spends its cash reserves. It is the most critical survival metric for startups and growth-stage companies, directly determining how long the business can operate before it needs additional funding or reaches profitability.

Cash runway is the number of months a company can continue operating at its current burn rate before running out of cash. It is the most direct measure of a startup's survival timeline.

Activation rate measures the percentage of new sign-ups who complete a key action that signals they have experienced the core value of the product. It is the bridge between acquisition and retention, and a leading indicator of long-term customer health.

Logo retention rate measures the percentage of customers (logos) retained over a given period, regardless of the revenue they generate. It provides a pure measure of customer satisfaction and product stickiness that is not distorted by revenue changes.

Customer acquisition cost (CAC) is the total cost of acquiring a new customer, including all sales and marketing expenses divided by the number of new customers gained in a given period. It is one of the most important unit economics metrics for any growth-stage business.

Customer lifetime value (CLV) is the total revenue a business can expect from a single customer account over the entire duration of their relationship. It quantifies the long-term financial worth of acquiring and retaining a customer, making it one of the most important metrics for sustainable growth.

Churn rate measures the percentage of customers or subscribers who stop using a product or service during a given time period. It is the most direct indicator of whether a business is delivering enough ongoing value to retain its customer base, and it has a compounding effect on growth, revenue, and customer lifetime value.

Completion rate measures the percentage of users who finish a defined process or onboarding flow from start to end. It is a direct indicator of how well a product guides users through critical workflows, and a leading signal of activation, retention, and downstream conversion.

Gross MRR churn rate measures the percentage of monthly recurring revenue lost to cancellations and downgrades in a given period. It isolates the revenue damage from customer losses before any offsetting expansion, providing the clearest view of how much revenue the business is haemorrhaging each month.

MRR closed vs quota measures the actual monthly recurring revenue closed by a sales team or rep as a percentage of their assigned quota. It is the definitive measure of sales execution against plan, connecting individual and team output directly to the revenue targets that drive business growth.

Net MRR churn rate measures the monthly recurring revenue lost to cancellations and downgrades minus the expansion revenue gained from existing customers, expressed as a percentage of starting MRR. It reveals whether the existing customer base is shrinking or growing in value each month.

Net MRR growth rate measures the month-over-month percentage change in net monthly recurring revenue. It captures the combined effect of new customer acquisition, expansion, contraction, and churn in a single number, making it the most comprehensive measure of SaaS revenue momentum.

Signup to subscriber conversion rate measures the percentage of free signups who convert to a paid subscription. It is the critical bridge between acquisition and revenue in product-led growth models, determining how effectively a business monetises its user base.

Net revenue retention (NRR) measures the percentage of recurring revenue retained from existing customers over a given period, including expansion, contraction, and churn. An NRR above 100% means existing customers are generating more revenue over time, creating a compounding growth engine that does not depend on new acquisition.

Revenue churn rate measures the percentage of recurring revenue lost from existing customers during a given period due to cancellations and downgrades. It captures the financial impact of customer losses in a way that simple logo churn cannot, because not all customers contribute equally to revenue.

Trial conversion rate measures the percentage of free trial users who convert to a paid subscription. It is the bridge between product-led acquisition and revenue, revealing whether your trial experience delivers enough value to persuade users to pay.

Customer renewal rate measures the percentage of customers who renew their subscription or contract at the end of its term. It is the most direct measure of whether customers find enough ongoing value to continue paying, and it is the foundation of predictable, recurring revenue.

Add-on revenue analysis measures the total revenue generated from optional extras attached to subscription plans. It reveals which add-ons drive the most incremental value, how attach rates evolve over time, and whether your catalogue structure is converting upsell opportunities effectively.

Cohort retention analysis groups subscribers by the period they signed up and tracks the percentage that remain active over subsequent months. It reveals whether retention is improving for newer cohorts or whether aggregate figures are masking deterioration beneath the surface.

Coupon redemption rate measures the percentage of issued coupons that are actually applied to subscriptions. It is the primary indicator of whether promotional campaigns reach the right audience with compelling offers or waste budget on discounts that go unused.

Customer churn rate is the percentage of subscribers who cancel their subscriptions within a given period. It is one of the most important health indicators for any subscription business because even modest churn compounds quickly, requiring ever-larger acquisition volumes just to maintain flat revenue.

Customer segmentation analysis groups subscribers by attributes such as plan tier, billing frequency, geography, or revenue contribution. It identifies high-value segments, surfaces behavioural patterns, and enables tailored pricing, onboarding, and retention strategies instead of one-size-fits-all approaches.

Plan performance analysis evaluates how each subscription plan contributes to revenue, growth, and retention. It compares plans on metrics such as adoption rate, ARPU, churn, and upgrade/downgrade patterns to reveal which tiers are working and which need restructuring.

Plan upgrade rate measures the percentage of subscribers who move to a higher-value plan within a given period. It is a key indicator of product value realisation and expansion revenue potential, representing the most capital-efficient form of revenue growth because upgrades require no acquisition cost.

Revenue cohort analysis tracks the revenue contribution of subscriber groups over time, grouped by sign-up period. Unlike customer retention cohorts that count heads, revenue cohorts account for expansions and contractions, revealing whether subscribers become more or less valuable as they mature.

Seasonal revenue trends analysis identifies recurring patterns in subscription revenue, sign-ups, and churn across calendar periods. It distinguishes genuine growth or decline from predictable cyclical fluctuations, enabling more accurate forecasting and better-timed campaigns.

Subscription lifecycle analysis maps the complete subscriber journey from trial or initial sign-up through activation, expansion, renewal, and eventual cancellation. It identifies conversion rates and drop-off points at each stage, ensuring teams optimise the whole funnel rather than a single stage in isolation.

Subscription churn rate is the percentage of active subscriptions that are cancelled within a given period. It is a core indicator of product-market fit and customer satisfaction, and the primary drag on subscription growth. Even high acquisition cannot overcome high churn, making it the most leveraged metric for sustainable recurring revenue growth.

Subscription upgrade rate is the percentage of subscribers who move to a higher-value plan within a given period. It reflects the effectiveness of upsell motions and pricing tier design, and drives expansion revenue at zero acquisition cost.
